IMPROVEMENT IN ADJUSTABLE CARRIAGE-POLE.

flit: fitlpetth referrer it in iljtfit who; fitment zmt mating art at the 8211M- TO ALL WHOM IT MAY CONCERN:

Be it known that I, M. A. K001i, of Catskill, in the county of Greene, and State of New York, have invented a new and useful Improvement in Adjustable Garriage-Poles; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 represents a plan or top view of my improve d adjustable carriage-polo. Figure 2 is a vertical longitudinal section of the same, taken on the plane of the line a; :0, fig. 1. Figure 3 is a detail vertical transverse section, onan enlarged scale, of the same, taken on the plane of the line y y, fig; 1.

Similar letters oi reference iudicatelike parts. This invention relates to that class of carriage-poles which can be adjusted to carriages, sleighs, or other vehicles, in which the'clips may be. set any suitable distance apargand to any length of axle. The present invention is more particularly intended as an improvetnenton the adjustable carriage-pole,

for which Letters Patent, No..39,'4=15, were granted to Leman C. Miner, on the 4th day of August, 1863.

The object of the present invention is to prevent the segmental divided brace from working loose in the binding-clip, by which its two parts are secured to the pole; also to keep and secure them in the relative position to which they may have been adjusted, and to simplify the general construction of the whole apparatus.

A, in the drawing, represents the wooden pole. ,B is the curved rear extension of the same. The extension B is made of malleable iron, or other suitable metal or material, and is separately attached, either by means of bolts, rivets, or otherwise, to the rearend of the pole.

By this arrangement the construction of the pole is already greatly simplified, as it can be straight, and as an ordinary pole can be easily fitted to the extension B, in the manner shown.

Vehicles, already in use, by this arrangement have their poles made adjustable without requiring new poles.

The rear end of the extension B has a horizontal aperture, through which the circular slides, or arms 0 G, that project from the braces D, are fitted. v

The braces D D are pivoted to the under side of the pole or of its extension, in suitable manner.

The arm 0 rests upon the arm G, as in fig. 3. The contiguous faces of these arms are roughened or toothed, as is clearly shown in fig. 3, so that they cannot slide upon each other when once adjusted. They are clamped by means of a screw, a, which is fitted through the upper or under side of the extension B, as shown in fig. 2. The outer face of that arm, 0 or C, with which the end of the screw a course in contact, is provided with indentations b b, as shown, for the purpose'of preventing the said arm from slipping under t the screw,

By this whole arrangement any desired position.

In the aforesaid pole of L. Miner, the clip was formed by means of a U-shaped metal bar, fitted around the arms C G, and through the pole-extension. By the constant wear, the arms would soon work loose in the said U-shaped bar, and the tongue would swing and be unsteady.

The vibrating socket-joint connections (1 d are pivoted or fastened to the braces D D, in the ordinary or of arranging the arms and the clip, the whole device can be securely held in in suitable manner. 7

Having'thus described my invention, I claim as new, and desire to secure by Letters Patent- 1. Making the extension B, through which/the arms G C, of the swinging braces D D pass, separate from the pole itself, substantially as herein shown and described.

2. The arms 0 G, constructed. as described, and attached. directly in the pole-extension, by means of a horizontal aperture fitted through, and a screw,'a, fitted intothe same, as set forth.

3. Making thecontiguous surfaces of the arms 0 C rough or toothed, as set forth,.and forming indentations 6 b, or their equivalents, on the outer face of one of them, substantially as and for the purpose hereinshown and described.
